Book excerpt: World Class IT Technology is all around us. It is so pervasive in our daily lives that we may not even recognize when we interact with it. Despite this fact, many companies have yet to leverage information technology as a strategic weapon. What then is an information technology executive to do in order to raise the prominence of his or her department? In World Class IT, recognized expert in IT strategy Peter High reveals the essential principles IT executives must follow and the order in which they should follow them whether they are at the helm of a high-performing department or one in need of great improvement. Principle 1: Recruit, train, and retain World Class IT people Principle 2: Build and maintain a robust IT infrastructure Principle 3: Manage projects and portfolios effectively Principle 4: Ensure partnerships within the IT department and with the business Principle 5: Develop a collaborative relationship with external partners The principles and associated subprinciples and metrics introduced in World Class IT have been used by IT and business executives alike at many Global 1000 companies to monitor and improve IT's performance. Those principles pertain as much to the leaders of IT as they do to those striving to emulate them.
